Common Mistakes
Learn what NOT to do. These mistakes cause injury, illness, and death. Our builder prevents all of these.
Why This Matters
These aren't minor issues - they're life-threatening mistakes that cause suffering and death. Our builder automatically blocks dangerous configurations, but understanding WHY helps you make better decisions and recognize when products or advice are unsafe.
Using Heat Rocks
Heat rocks can reach temperatures over 120°F and cause severe burns, even with thermostats. Geckos cannot sense heat from below and will sit on them until injured.
Why This Is Dangerous
Leopard geckos evolved to sense heat from above (the sun), not below. Heat rocks can cause third-degree burns in minutes.
Safe Solution
Use overhead heating (halogen bulbs or deep heat projectors) with a thermostat. This mimics natural basking behavior.
Research-Backed
Reptile burns are a leading cause of veterinary visits. Heat rocks are responsible for the majority of these cases.
10-Gallon Tanks
10-gallon tanks are too small for adult leopard geckos. They cause chronic stress, prevent proper thermoregulation, and lead to health issues.
Why This Is Dangerous
Leopard geckos need space to thermoregulate (move between hot and cool areas). A 10-gallon tank is only 20" x 10" - barely enough room for one hide, let alone three.
Safe Solution
Minimum 20 gallons (30" x 12" x 12"), but 40 gallons (36" x 18" x 18") is recommended for optimal welfare.
Research-Backed
Studies show that reptiles in undersized enclosures exhibit increased stress hormones and reduced activity levels.
Calcium Sand Substrate
Calcium sand causes impaction (intestinal blockage) when ingested. It clumps when wet and cannot pass through the digestive system.
Why This Is Dangerous
Geckos may intentionally or accidentally ingest substrate while hunting. Calcium sand is marketed as 'digestible' but it's not - it hardens in the gut.
Safe Solution
Use safe substrates: paper towels (easiest), tile, or properly prepared loose substrates (not calcium sand).
Research-Backed
Impaction from calcium sand is a common cause of death in leopard geckos. Veterinary case studies document this repeatedly.
No Thermostat
Unregulated heat sources can reach dangerous temperatures, causing burns or overheating. Every heat source MUST be connected to a thermostat.
Why This Is Dangerous
Heat bulbs can exceed 150°F without regulation. A thermostat prevents temperatures from rising above your set point, protecting your gecko.
Safe Solution
Always use a thermostat with any heat source. It's not optional - it's essential safety equipment.
Research-Backed
Unregulated heating is the #1 cause of reptile burns and heat stress in captivity.
Only One Hide
Leopard geckos need three hides: hot, cool, and moist. A single hide prevents proper thermoregulation and causes stress.
Why This Is Dangerous
Geckos need to move between temperature zones throughout the day. Without options, they can't regulate their body temperature properly.
Safe Solution
Provide three hides: one on the hot side, one on the cool side, and one moist hide (with damp substrate) for shedding.
Research-Backed
Proper thermoregulation is essential for digestion, immune function, and overall health in reptiles.
